Borealis BH381MO Polypropylene Heterophasic Copolymer
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer
Material Notes:	BH381MO is a heterophasic copolymer. This product is characterized by an optimum combination of very high stiffness and high impact strength. This grade uses Borealis Nucleation Technology (BNT) to increase productivity by cycle time reduction. BNT in combination with excellent stiffness and good flow properties creates a high potential for wall-thickness reduction. Products originating from this grade have very good demolding properties, well-balanced mechanical properties, excellent dimension consistency with respect to different colors and good organoleptic properties. Cas No. 9010-79-1 Applications: Boxes and crates Technical parts Foaming applications Thin wall packaging Houseware Foamed food packaging Pails Special features: High stiffness Very good flow behavior High impact strength Information provided by Borealis AG
